The Plymouth Creek Restoration Project will improve water quality in Plymouth Creek and Medicine Lake, the creek's primary receiving water. The project will reduce total phosphorus and suspended sediment in Plymouth Creek and Medicine Lake stemming from streambank erosion. Streambank erosion is a common source of pollution, particularly in developed landscapes where flows in streams are considered flashy and can easily scour unprotected and disturbed streambanks.
This project engages private property owners including non-profits, businesses, and institutions, in the Harrison Neighborhood of Near North Minneapolis to install storm water best management practices. The BMPs will reduce pollution in Bassett Creek including chlorides and bacteria, for which the creek is impaired. The primary focus is on Glenwood Avenue, a focal point in the community and a highly impervious area.
The Becker County Drainage Ditch Inventory and Inspection Project is a collaborative, multifaceted approach to develop a GIS-based drainage ditch inventory database system, inventory the current conditions of judicial ditches and adjacent land, and target and prioritize portions of each ditch system for restorative or protective measures.
Installation of a 43,000 sf infiltration gallery in Becker Park in the City of Crystal to infiltrate 0.5 inches of runoff from a 147 acre currently untreated mixed use subwatershed with 51% impervious surface. The project will reduce total phosphorus to Impaired Water Upper Twin Lake by 118 pounds annually, and reduce street flooding on Bass Lake Road (Hennepin County Road 10).
With over 500 public water lakes in Becker County, we are blessed with abundant and diverse lake resources that, like those of much of lake country, are at risk of degradation due to increasing development pressures, redevelopment of non-conforming lots, rising stormwater runoff and land use changes within their watersheds.
Beltrami County will be updating their water plan in 2017. This plan will be watershed protection oriented and will utilize all available data and maps in order to best protect our water resources. In 2012, Beltrami County completed screening on 19 of our large lakes with heavy land use development. What we found was that none of the lakes had enough chemical data for a trend analysis.
The Beltrami SWCD proposes to partner with citizen and non-profit groups to complete projects that will reduce stormwater runoff and retain water on the land. The majority of the projects will be in the Lake Bemidji lakeshed which has recently been identified in the WRAPs project as being on the verge of impaired for nutrients. With the City of Bemidji being a regional hub for Northwestern Minnesota and the First City on the Mississippi, there are ample opportunities for citizen involvement and ample opportunities for stormwater improvements.
As a part of the Mississippi Headwaters Stormwater Retrofit Analysis, a feasibility study was conducted on the Bemidji State University property to determine possible subsurface water quality best management practices options. Staff from Beltrami SWCD, in cooperation with the City of Bemidji and Bemidji State University, are proposing to install a subsurface stormwater treatment system to reduce Total Suspended Solids (TSS) and Total Phosphorus (TP) loading to Lake Bemidji and subsequently the Mississippi River.
Recent efforts by Carver County Water Management Organization Staff have centered on removing point sources of bacteria in both Bevens and Carver Creeks. These efforts have shown improvement in water quality; however the creeks are still above the state standard for E. coli. Early results from field surveys have pinpointed areas where livestock have uncontrolled access to streams. Five sites over a twenty mile stretch of Bevens Creek have shown evidence of livestock access to streams and associated damage to streambanks.
The Crow Wing Soil and Water Conservation District (SWCD) proposes to complete stormwater best management practices (BMPs) that will reduce 40 pounds of phosphorus and 40 tons of sediment per year from entering Big Trout Lake. The Crow Wing County (CWC) Water Plan identifies Big Trout Lake as a priority lake to enhance due to its significant decline in water clarity and high ratio of impervious surface surrounding the lake. The 2015 CWC Assessors Property Tax Assessment reports that Big Trout has the second highest taxable land value in CWC at $4,200 per foot of shoreline.
The funds requested will provide Big Lake Township with the technical and financial assistance necessary to retrofit up to six locations for stormwater treatment practices within the direct drainage area of Birch Lake, an impaired water body which is very close to meeting state standards. The projects have been identified as high priority in several water quality plans including a TMDL, a subwatershed assessment, the County Water Plan and the Mississippi River (St. Cloud) WRAPS.
The Birdie Lane East Ravine Improvement project consists of eliminating ravine erosion and treatment of an 8.24-acre watershed to reduce total phosphorus reaching Lake Hazeltine by 98 pounds per year. The eroding ravine will be replaced with a linear treatment feature to provide treatment of a watershed that has land uses that include roads, single-family residential, and a golf course. The project will involve development of a cascade, pool, and riffle channel system.
This project will focus, on a sub-regional scale, on water quality improvements targeted at concentrated runoff flows generated from upstream, developed portions of the City of Forest Lake. This project will work to modify an existing wetland complex located in publicly owned Bixby Park of Forest Lake to increase water quality treatment potential and storage capacity. The project will also incorporate an innovative iron-enhanced sand filter which will remove dissolved phosphorus, resulting in a 206 pound/year reduction of phosphorous and a 27 tons/year removal of sediment.
Prevention of groundwater contamination from unused, unsealed wells is identified as a priority in the 2020-2030 Dakota County Groundwater Plan. Dakota County plans to prevent groundwater contamination, especially in drinking water supply management areas, by completing a well inventory in the Black Dog Watershed area to identify suspected abandoned wells, and provide 50% cost-share grants to seal approximately 13 unused, unsealed wells in the watershed.
This project will reduce sediment to the Minnesota River, and protect private land and public infrastructure. Blakeley Trail (County Rd 60) in southwest Scott County is surrounded by deep ravines. As these ravines incise, they cause road shoulder landslides, which cut into private property, threaten the road at the head-cuts and generate sediment which creates maintenance and flooding issues downstream. The Scott Watershed Management Organization and the Scott County Highway Department have partnered on this project because of the multiple benefits.
In South Minneapolis, the water quality of Diamond Lake has suffered in recent decades. In fact, the Minnehaha Creek Watershed District's (MCWD) analysis of water testing results designated the water quality grade as F. This is largely a result of water that rolls off roofs, yards, and streets in the 690-acreDiamond Lake watershed and ends up in the lake - bringing pollutants, debris and dirt with it.
The goal of this project is to reduce the number of vulnerable unused wells located within sensitive areas and to prevent potential groundwater contamination. Most Minnesotans rely on groundwater as their primary source of drinking water. Unused and improperly sealed wells can serve as an open conduit to groundwater aquifers, allowing surface water runoff, contaminated water or improperly disposed waste to reach an uncontaminated aquifer. Properly sealing unused and improperly sealed wells is a preventive practice that protects groundwater aquifers from contamination.
The purpose of this project is to expand the County's long standing well sealing efforts by reducing the current inventory of identified well sealing projects.
With limited funds and limited staff time available for targeting critical service areas and implementing Best Management Practices (BMPs), Geographic Information System (GIS)-based tools that pinpoint locations where BMPs will have the highest effectiveness are increasingly important. The Blue Earth County/SWCD Watershed Implementation Targeting project will utilize LiDAR topographic data to determine areas of high importance for BMP implementation. The county is located in the Blue Earth, LeSueur, Watonwan and Middle Minnesota watersheds where there is a high density of impaired waters.
This project will conduct Inventory and Inspection of four drainage ditches in Blue Earth County: JD116, CD5, CD86 and CD56. The inventory of these drainage ditches is important in order to identify where erosion, sediment and/or nutrients contribute substantially to water quality degradation. The project will also prioritize sites for future side inlet control, buffer strip implementation, and/or storage and treatment implementation.
Vegetated buffer and filter strips along waterways is a practice that addresses many surface water concerns. Establishing permanent vegetation along waterways is an implementation priority in the Blue Earth County Water Management Plan and required by local ordinance and Minnesota Rules. Minnesota Shoreland Rules, Chapter 6120 and the County Shoreland Ordinance contain standards for agricultural uses in shoreland. Agricultural uses are permitted in shoreland areas if steep slopes and shore and bluff impact zones are maintained in permanent vegetation.
Ravine, stream bank and bluff erosion contribute significant amounts of sediment to rivers and streams. The MPCA report, Identifying sediment sources in the Minnesota River Basin, found the Blue Earth and Le Sueur watersheds contribute as such as half of the sediment to the Minnesota River, even though they account for only one-fifth of its drainage area. These watersheds contain the majority of the bluffs in the basin as well as many large
ravines.
Seminary Fen, a 600-acre complex in Carver County, supports one of only 500 calcareous fens in the world and is one of the highest quality calcareous fens in southern Minnesota. The Fen feeds Assumption Creek; one of the metro area's last known trout streams that supports naturally reproducing native brook trout. Assumption Creek then discharges to the nearby Minnesota River. The Fen's unique hydrology, soils, plants, and habitats are highly sensitive to water quality and sedimentation stress.
In 2002 and 2004, the Minnesota Pollution Control Agency listed Bluff Creek for turbidity and biological integrity. A Total Maximum Daily Load report and implementation plan were finalized and approved in 2013. This project was identified as a high priority site for culvert restoration and bank repairs.
The purpose of this project is to complete a feasibility study to determine the best sites for projects in the Boot Creek headwaters, in the Le Sueur River watershed, to reduce erosion and pollutant loading. The study will identify critical source areas and provide additional watershed information to assist in prioritizing locations to address local resource management and water quality goals.
In recent years, nutrient enrichment has occurred in Lake St. Croix due to increasing amounts of phosphorus entering the lake from the watershed. According to the TMDL, approximately half of the phosphorus-loading to Lake St. Croix is in the soluble form, and agriculture has been identified as one of the largest contributors of that phosphorus. In addition to the TMDL, subwatershed analyses were completed to identify, assess, and prioritize phosphorus-reducing practices in rural areas draining to Lake St. Croix in Washington County. This project will reduce phosphorus discharges to the St.
This project proposes the implementation of 10 best management practices identified as having the lowest cost-benefit ratio as it relates to phosphorus reduction to downstream Moody and Bone Lakes with an estimated reduction to watershed phosphorus loads to Bone Lake by 90 pounds per year and to Moody Lake by 24 pounds per year. The Bone Lake watershed is at the ?top? of the larger watershed, making it an ideal location to begin work that will have direct improvements downstream.
Bone Lake and upstream Moody Lake are the headwaters of the Comfort Lake-Forest Lake Watershed District northern flow network, and as such, their water quality sets the stage for downstream waters, particularly Comfort Lake, the Sunrise River, and ultimately Lake St. Croix. This project proposes the implementation of six wetland restorations located along the tributary identified as the single highest source of phosphorus loading to Bone Lake. These wetland restorations are estimated to reduce watershed phosphorus loads to Bone Lake by 50 pounds per year.
Healthy communities and healthy water is a priority in Crow Wing County (CWC). The County and the Crow Wing Soil and Water Conservation District (SWCD) propose to enhance and improve the water quality of Little Buffalo Creek, a tributary to the Mississippi River. The SWCD will partner with CWC, the City of Brainerd, citizens, Central Lakes Community College, and the Minnesota Department of Natural Resources to complete raingardens, shoreline stabilizations, and bioretention areas within the Little Buffalo Creek subwatershed.
Based on the Minnesota Waters Lake and River Association database, Crow Wing County has the highest number of lake associations in Minnesota. Currently, there are over 136 lake association groups in the county, which does not include neighborhood, resort or religious groups. These lakes aer a cornerstone to the state's tourism econmy and there is a great demand for stormwater management incentive program to protect these local water resources.
